@makeda_mansa Bonjour. Non pas d'erreur, la commande "nc" (pour netcat) doit marcher si le bon package est installé. Mais "ncat" devrait aussi fonctionner : il existe en effet plusieurs implémentations de Netcat.
#ECSC2024 | Accompagnée des coachs de l'ANSSI, la @ECSC_TeamFrance 🇫🇷 est arrivée à Turin, prête à affronter les épreuves de l'European Cybersecurity Challenge. 💪 N'hésitez pas à les encourager en commentaire !

@nneonneo @ACMUIST Congrats Robert, that is very impressive!🔥If you still have some energy and want to continue on French CTF, we are launching the #FCSC2024 tomorrow with a lot of pretty tough challenges (rev, pwn, crypto, etc.). We'd love to have you there :-) ▶️france-cybersecurity-challenge.fr
@Sylv1_Durif @ANSSI_FR Non, aucune résolution légitime sur #Hackropole ne demande de regarder les sources des images Docker. Il faut accéder aux services via les ports exposés, et trouver une manière pour extraire les flags comme cela. Bon courage ! 🏛️
